SPECIFICATION forming part of Letters Patent No. 447,996, dated March10, 1891.

Application filed June 26,1890, Serial No- 356,849- (No model.)

To all whom it may concern:

Be it known that I, McOLINrooK YOUNG, of Frederick, in the county ofFrederick and State of Maryland, have'invented certain Improvements inBrushes, of which the following is a specification.

This invention has reference more particularly to that class of brushesrepresented in Letters Patent of the United States No. 423,506, grantedto me on the 18th day of March, 1890, in which metallic fasteners aredriven in to the face of a brush-block in such form and manner that eachfastening serves to retain a series of tufts in holes bored in the blockor body.

The object of the present invention is to reduce the cost of thefastening devices and to admit of their being the more firmly secured inposition ;-and to this end it consists, essentially, in a sinuous orserpentine fastening, preferably formed of wire, with a series of teethor projections adapted to extend down.

within the tuft-receiving holes.

Referring to the drawings, Figure l represents my improved fastening inits preferred form. Fig. 2 is a perspective View of aportion -of thebrush with one end shown in cross-section through a row of tufts toexpose the fastenings to view. Fig. 3 is a longitudinal section throughthe brush on the line 3 3 of Fig. 2. Fig. 4: is a face View of a portionof a brush-body with my fastening applied thereto,

the tufts being omitted in order that the position of the fastener maybe plainly shown.

Referring to the drawings, A represents a brush block or body,preferably consisting of a single block of wood having in its face aseries of holes a, arranged in rows, and each adapted to receive afolded or doubled tuft B in the ordinary manner.

C represents a fastening device consisting of a wire or slender metallicstrip bent to and fro in such manner as to produce a series of U-shapedportions 0, connected at their up per ends by intermediate portions 0'.The portions 0 are adapted each to extend down into one of thetuft-receivingholes within the bight or fold of the tuft to hold thelatter down to its place within the body. In order that they may themore firmly hold the tuft-s and to prevent the tufts from workingoutward from under them, the portions 0 are preferably made concave atthe lower end in order to straddle or embrace the tufts, as shown in thedrawings. The upper portions 0 are adapted to span the upper edge of thewall or portion. of the block between the adjacent tuft-holes.

In making use of the device its series of projections c are drivendownward tightly into the adjacent holes in the line of tufts, asplainly shown in Figs. 2, 3, and 4.

In inserting the fastener I prefer to seat its vertical arms firmlyagainst or within the side walls of the holes, and in order that thefastener may be held the more firmly in position I propose to providethe vertical arms with teeth or serrations c to engage the wood.

\Vhile the fastener may be punched or cut from sheet metal,I find itadvisablefor many reasons to construct it of wire, which is accomplishedby taking a single piece of wire of suitable length and diameter,preferably steel wire of moderate temper, and bending the same into therequired form. As these portions which enter the tuft-holes, and whichmay be considered individual fasteners, are connected by the portions 0,the fastener serves to tie the block together laterally, and in theevent of the portion which holds one tooth failing to take a firm holdin the body it will nevertheless be retained in position through itsconnection with the adjacent portions.

One of the advantages of the present construction lies in the fact thatspaces 0 which exist between the top connecting portions 0', permit thetwo sides of the tuft to close compactly together, so that the exposedportion of the tuft presents a close compact body of fibers or bristles.In this regard the fastening is superior to the one represented in mypatent above referred to.

Having thus described my invention, what I claim is- 1. Afastener forsecuring tufts in series in a brush-block, consisting of a narrowsinuous strip presenting on one edge the projections to enter thetuft-holes and bear within the bight of the tufts and on the other edgethe notches or openin whereby the two sides 0t caeh tuft are permittedto close together through theprojection by which they are held.

2. The improved tuft-fastener for use in brushes, consisting of a wirebent as described to pre ent aseries of tuft-holding projections.

The tuft-fastener for use in brushes, consisting of the sinuous striphaving the projections adapted to enter the tuft-holes and bear withinthe tufts, and having also the teeth or notches c to engage the wallsbetween the tuft-holes.

4. The improved brush consisting of the block or body provided with aseries of holes,
